Predicting the energy output of a bifacial photovoltaic (PV) module is usually not as straightforward as for a monofacial module. The problem usually lies in the estimation of the back-side irradiance which strongly depends on the mounting conditions, tracking or fixed positioning and variable ground albedo. We developed a new direct-diffuse power rating model for predicting the energy yield and performance ratio of bifacial photovoltaic modules (DDPRbifi). The model was validated on 16 bifacial monocrystalline silicon modules of three silicon PV technologies (SHJ, IBC, TopCon) and monitored at four different locations in Europe. The new model shows the best accuracy on all PV modules regardless of the module technology and monitored location. On average, the discrepancy between the simulated and measured performance ratio of the observed modules is around 2 %.
